This housing unit accepts a shaft diameter of 20 mm and is designed for use with bearing HC 204. Weight is 0.57 kg, which is relevant for handling and mounting but does not indicate load capacity. Dimensions read from the catalogue drawing are as follows: A = 62 mm, B = 43.5 mm, E = 90.0 mm, G = R 1/8, K = 11.5 mm, L = 112 mm, b = 20.0 mm, c = 11 to 12.8 mm, B1 = 46.5 mm, B2 = 31.0 mm, c0 = 6.6 mm. These values can be checked against the technical drawing on the product card for exact mounting layout. The housing belongs to the OIH series and is intended to hold the HC 204 bearing insert in a fixed position on the shaft line, with the G dimension marking the grease fitting thread for lubrication access. The construction allows mounting where the listed A, B, E and L dimensions match the surrounding structure, and the b and c values are relevant for base and fixing hole alignment during installation.
